BA'LlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 244,448, dated July 19,1881.

Application filed May 6, 1881. (No model.) i

To all whom it may concern:

Be it known that I, JAMES N. GRANT, of O0- lumbus, county of Esmeralda,State of N evada,have invented an Improved Baling-Press; and I herebydeclare the following to be a full, clear, and exact descriptionthereof.

My invention relates to certain improvements in baling-presses; and itconsists in a peculiar and novel construction andarrangement of conicalpulleys, whereby I am enabled to operate the follower with an economy inpower; and in a novel construction and means for automatically openingthe side doors of the press and,lastly, in a novel means of securing andopening the top door and of supporting it in position when opened, allof which will hereinafter more fully appear.

Referring to the accompanying drawings, Figures 1 and 2 are perspectiveviews of my baling-press.

Let A represent the frame or chamber of the press, supported on anappropriate base, 13, and having the follower 0, adapted to travelwithin the chamber or press by means of the end lugs or guides, D,fitting through slotsE in the sides of the press. Connecting with theguides D are the pulleys F, and journaled near the top of the press andto one sideare stationary pulleys Gr. r I

On the back of the press, near the bottom, is journaled the shaft H,extending across and to each side. Upon the ends of this shaft, on bothsides of the press, are. the conical pulleys I I, rigidly secured to theshaft. These pulleys have their smaller or apex ends toward the pressand increase their spiral circumference outward away from the press.Upon the end of the shaft H, outside the pulley I, is secured the largedriving conical pulley J. This pulley, with relation to its spiralcircumference, is oppositely placed to the smaller pulleys I I, 'ithaving its base or greater circumference nearer the press and graduallydecreasing outwardly away from said press.

I attacha rope, K, on one side of the press to its top, as shown at a.These ropes pass down under the pulleys F, attached to the follower,thence up over the stationary pulleys G, and thence down to the conicalpulleys I I, and are attached to the largest and outer circumference orface of said pulleys, so that when also gained.

said pulleys are turned the ropes K will wind around the largest facesof the pulleys from the outside in toward the'apex to the smallest faces-or circumferences.

I attach a rope, L, to the driving pulley J at a point upon its innerand larger circumference orface, and wind itthence outwardly away fromthe press to the smallest circumference on said pulley J. Suppose thefollower tobe at the bottom of the press.- The hay is put in the pressin the usual manner. The rope L about the large pulley J is woundthereon. Power is applied to the end of the rope L. Asit unwinds fromthe smaller faces of its pulley it causes it to turn rapidly, and theropes K, in winding upon the larger faces of the pulleys I I, are thusmade to conform to the same speed, and the follower is raised rapidly.As the rope L begins to reach the larger faces of the pulley J there isa decrease of speed but an increase in power, and the ropes K, windingtoward the inside smaller circumferences of the pulleys I I, conform tothe slower speed, and an increase of power is At the first part of therise of the follower the hay, being loose, does not require muchpressure, so that power can be sacrificed to speed. As the pressurerequires to be increased the speed is lowered, and both pulleys giveincreased power.

I am aware that it is not new to use conical pulleys for the purpose ofapplying graduated power, and that such have been applied to operatepresses to accomplish the result herein set forth. Their use heretoforehas been confined, however, to a single set of such pulleys, and thedriving-pulley has been a large pulley of ordinary shape with but onecircumference. In the operation of such devices there has therefore beenspeed at first and increased power afterward as a result of the singleset of conical transmitting-pulleys, and the driving-pulley has hadnothing to do with the inverse graduation of power and speed, thoseremaining as far as it was concerned constant factors; but with mydevice the'drivingconical pulley enters directly into the result,combining with the transmitting conical pulleys I I, to effect thisinverse graduation of speed and power.

- Another advantage in my device is as fol-. lows: Power is generallyapplied to presses by horses. These are attached to the operatingrope ofthe driving-pulley and travel away from the press. N ow, when thedriving-pulley has but one circumference, it is obvious that the ropemust be longer and the horses travel farther than when the pulley is aconical one, such as the pulley J herein. In the former power is appliedat first when it is not so much needed and speed is reduced. In thelatter the speed is increased, the rope shorter where it is needed, andthe loss of power at that time does not affect the result. This isimportant when a great many bales are to be made.

In my device, as compared wit-h those I have mentioned, I start in withgreater speed, make the horses go a shorter distance, and end with thesame power.

Let M M represent the usual side doors of the press, hinged to the frameappropriately at one end. The other ends are provided with rods N, onwhich are journaled or hinged the catches 0. These catches are made ofrods, and form with the rods I a quadrilateral figure or parallelogram,as shown. To the sides of the frame A are fastened projecting supportsor bearings I to which arejournaled rollers Q. When the doors are closedthe catches O fit over and behind the rollers Q, and the pressare uponthe doors from the inside exerted outwardly will not loosen the catchesfrom behind the rollers. Across the sides of the frame A, just below thebearings of the pulley G, is the transverse rod or lever B, journaledand supported appropriately so as to turn, and provided with arms 0 atits ends. These arms 0 fit under the catches O at about their middlewhen the doors are closed, and said catches are in position behind therollers Q.

The lever B is provided at its middle with a crank-arm, S, to which ispivoted a pitman, T, projecting downwardly, as shown. The end ofthispitman is provided with a screw, U, having a bifurcated or notchedhead. This screw, by inserting it in the pitman deeper or unscrewing it,varies the length of the said pitman, and thus adjusts it.

Extending outwardly from the traveling pulley I, attached to thefollower, is a pin, V.

The operation of this device is as follows: After the hay is put intothe press the doors M M are closed, and their catches O fit over andbehind the rollers Q and over the arms 0 of the lever-rod R, which saidarms, by the weight of the rod R, extend downwardly and parallel withthe catches 0. When the follower ascends the pin V comes in contact withand fits into the notch'ed end of the pitmanscrew U as it continues toascend, raises the pitman T, which turns the lever-rod It, and the arms0 are turned outwardly, thus pressing out the catches 0 from behind theroller Q and releasing them, so that the pressure of the bale withinwill cause them to spring open.

In order to adjust the arms 0 to make them work properly, I canplacesmall set-screws in them, the points of which project in front andimpinge upon the catches 0. Thus when an arm 0 becomes worn, by settingup the screws a little they can be adjusted.

By adjusting the pitman-screw U the pin V can be made to engagetherewith just at the proper time when the doors should yield to thepressure of the bale.

Let W represent the top door of the press. It is-hinged to a transverserod, X, attached to the frame A at one side, as shown. The top of thedoor W is provided with a bcam,Y, on the top of which and about themiddle is pivoted the lever Z, to which on each side of the pivotpointare pivoted the rods 1) b, extending to the ends of the beam Y, andprovided on their ends with loops 1', as shown. Guide-staples or eyes dd direct these rods properly. Secured in the top of the press on eachside are the bails f f, havin g an upwardlyprojecting arm, 9. Supports hIt just outside of these bales prevent them from falling down and keepthe arm g in an upright position. When the door or lid W is closed downthe loops 6 on the end of the rods b b fit over the arms 9 of the bailsf f. By turuin g the lever the bails will be drawn over the ends of thebeam Y and the lid secured. By turning the lever the other way the bailswill be pushed 0d the beam and the door unlatched.

The advantage in this construction is that the loops t'and the bails ff, by being always in position. to engage with each other,arepracticallyiconnected, and still allow the lid to be raised. A catchor rack, Io, holds the lever Z in place when the bails are drawn overthe beam Y. A brace, (marked 1,) fitting over pins on in the top of thepress, further guides and secures the door.

In order to prevent the lid W from falling back too far when'opened, Ihave the following novel device: To one end of the lid W is pivoted aplate, at, having on its end a flangesupport or socket, o. I Anotherplate, 1), is pivoted to the inside of the frame A, and also to thefirst plate, a, as shown. When the lid is closed the first plate extendsupward and the second is inclined to meet its upper end. When the lid isopened the two plates turn on each other about their pivot-point untilthe second plate, p, fits into the flange-support or socket 0, and bothare stopped and form a rigid connection and hold the door from fallingback.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a baling-press having a follower, O, and side doors, M M, thedevice for latching and automatically unlatching said doors, consistingof the hinged latches O, rollers Q, 1ever-rod R, with arms a, crank S,pitman T, with its forked head, and traveling pulley F, with its pin V,when arranged substantially as herein described.

2. In abaling-press having a hinged or swinging top door or lid, W, thedevice for locking said door in place and releasingit, consisting withits flan ge-support o, and plate 12, when arranged and constructedsubstantially as herein set forth. a

In witness whereof I have hereunto set my hand.
